Cheshire Damp Proofing offer a full damp-proof course service, as a horizontal barrier in a wall designed to resist moisture rising through the structure, a process known as rising damp.
A damp-proof membrane (DPM) performs a similar function for a solid floor. Moisture resistance is not necessarily absolute: it is usually defined by a specific test method, limits, and engineering tolerances. In simpler words, DPC is used to stop dampness in buildings.
